The AD8213 is a dual-channel, precision current sense amplifier. It features a set gain of 20 V/V, with a high common-mode voltage range, buffered output voltage, and wide operating temperature range. It is suitable for applications such as high-side current sensing, motor controls, transmission controls, diesel injection controls, engine management, suspension controls, vehicle dynamic controls, and DC-to-DC converters.
The AD8213 is a dual‑channel precision current‑sense amplifier designed for high‑side current sensing in automotive and industrial applications. It offers a fixed gain of 20 V/V, a wide common‑mode voltage range (‑2 V to +65 V), and a small 10‑lead MSOP package that operates from –40 °C to +125 °C.
The datasheet provides detailed specifications, absolute maximum ratings, pin descriptions, typical performance curves, and application notes for high‑side and low‑side current‑sensing configurations, as well as guidance on low‑pass filtering and ESD handling.
